“…Additionally, they evaluated the effect of variables such as ink types and printing conditions on the achieved GE. Gao et al [34] illustrated how specific geometry and size can be utilized to design meta-materials that generate vibrant and saturated colours that remain independent of the viewing angle. They offer a pioneering method for developing colourproducing systems that could potentially have far-reaching applications in diverse fields such as photography, printing, and displays.…”

With the development of display technology, more displays can cover the wider gamut, but most of the content they show is based on a small gamut. It is significant to employ gamut expansion (GE) to expand the small gamut images to a wider target gamut. Most of the existing GE methods only use global or local operations to realize the mapping from small gamut to wide gamut. However, the utilization of both global information and local feature is important for GE. In this article, the authors propose a combined global‐local gamut expansion network (G‐LGENet) for mapping the input standard RGB (sRGB) images to wider ProPhoto RGB space. In G‐LGENet, the global colour mapping module first extracts and fuses the global colour priors and learns the mapping of colour information for the corresponding pixels. And then, the local enhancement (LE) is designed to extract the local colour information between the corresponding pixel and neighbourhood pixels. The experimental results on a sRGB‐to‐ProPhoto dataset have demonstrated that the proposed G‐LGENet outperforms the other excellent GE methods qualitatively and visually.

“…[14][15][16] However, the inherent limitations of light extinction from single plasmonic nanostructures or monolayers often cause low optical contrast, far from satisfying real-world industrial requirements. [17,18] To address this, two rational approaches have emerged. First, coupling a monolayer of plasmonic nanostructures with a thin film resonator, commonly referred to as an etalon, substantially enhances reflective colors.…”

Plasmonic nanoparticles serve as nonfading pigments for vibrant outdoor glasses and smart windows, offering vivid colors under sunlight with exceptional spatial resolution. However, simultaneously achieving the desired plasmonic coloration in both reflection and transmission with a full‐color gamut remains a formidable challenge, especially when using a single fabrication method. Here, a facile physical triple co‐deposition method to construct scalable plasmonic superstructures, optimal for dichroic color engineering is demonstrated. A key feature of such all‐in‐one plasmonic superstructures lies in extensive color performance in transmission and reflection modes, spanning from transparent invisibility to vivid full colors across the wavelength range of over 600 nm. This exceptional coloration fidelity stems from their 3D‐stacked nanocomposite where plasmonic nanoparticles incorporate a random but uniform distribution within a glass matrix. Wafer‐scale rich and dynamic color images useful for colorful data storage and steganography, as demonstrated through layer‐by‐layer color painting with combinatorial plasmonic superstructures are shown.

“…15 The enhanced possibilities of plasmonic colours have actually attracted much attention recently, leading to the development of applications from metasurfaces with various lithographic plasmonic nanostructures on surfaces. 5,[16][17][18][19] A patent was filed on the process of producing bichromatic materials. 20 The developments are much more limited for plasmonic colours observed in diffusion or reflectance.…”

“…The scattering of plasmonic surfaces or metasurfaces has been addressed. 16,21 However, in the literature, and to our knowledge, there is no example of prediction and calculation of the diffused spectra of plasmonic bulk materials. Scattering cross sections of individual plasmonic nanostructures were calculated, but the colour of a bulk material containing such nanostructures was not investigated.…”
